For a first jam, it's not bad at all! ^^
As other commenters said, the controls are very difficult to figure out, you should add a basic tutorial in the game description. Because once you understand how to play, it's a nice relaxing game!
The visuals are pretty unique, both in a good and bad way: I'm not a fan of the character's design, but the die and environments have their own style!
Good job on the submission! =)
